To all whom t may concern.'

Be it known that l, .lasen G. VINCENT, a citizen of the United States,and resident of Detroit, Wayne county, State of Michi- |van, haveinvented certain new and useful improvements in H drocarbon-Motors, ofwhich the following 1s a specication.

'lhis invention relates to the making of motor 4cylinders andparticularly to the forming of cylinder blocks and to connecting variousparts of built up cylinders.

Une of the objects of the invention is to connect metal parts by a novelmethod or process.

Another object of the invention is to build up a motor cylinder by anovel method.

Another object of the invention is to provide a novel jacketed cylinderconstruction of extremely light weight and great strength.

Another object of the invention is to provide acylinder block made up ofseveral cylinders and connected water jacket.

@ther objects of the invention will appear from the followingdescription, taken together with the drawings which form a part of thisspecification, and in which Figure l isa side elevation and partvertical section of a block of motor cylinders made accordin to thisinvention;

Fig. 2 is a p an view of the block of cylinders shown in Fig. l, withthe cam shaft housing removed therefrom;

Flg. I9 is a perspective view of a forging or castlng forming a langepiece which is attached to one of the elbows;

Fig. 10 1s a fragmentary view illustratin the method of forming one ofthe welded joints between the cylinder and water jacket; Fig. 1lillustrates the method of forming the welded joint between one of theelbows andthe cylinder proper, and

Fig. l2 illustrates a method similar to that shown in Fig. ll.

Referring to the drawings, Figs. l and 2 represent a cylinder block Badapted to be used as part of a hydrocarbon motor. As shown, the' blockis made up of three cylinders indicated at 20, and they are joinedtogether as bv welding at their bottom Hanges, the welded joints beingshown at 2l in Fig. l. The cylinders are surrounded by a water jacketwhich is made up of two parts joined together and to the cylinders aswill be more fully hereinafter. described. Une of these water jacketparts 22 is shown in Figs. 3 and 5 and it will be understood that thetwo parts are identical except that one of them may have tubes 23secured thereto for the purpose of feeding water to or from the spacebetween the water jacket and the cylinders. By joining these two jacketparts together and to the cylinders all of the parts are thus boundtogether to make a rigid cylinder block.

ln Fig. 4L there is illustrated, partly Vin elevation and partly insection, a complete cylinder built up of various parts in accordancewith this invention. This cylinder is of the overhead valve type, and itwill dll be understood that they may be built up separately or in pairsor three in a block as desired for' the particular conditions underwhich they are used. For the purpose of illustrating this invention thecylinder shown in Fig. 4- may be referred to as one of the cylinders ofthe cylinder block shown inv Figs. 1 and 2, and it will be so described.

The cylinder 2'() is preferably made of a steel forging machined bothinside and outside and formed with a llange 24 at its lower or outer endfor the purpose of attaching it to a crank case or to adjacentcylinders,with a combustion space 25 at its upper or lnner end, and withinlet and outlet ports 26 and 27 respectively and spark plug ports 28communicating with the combustion space. The s ace 25 is of slight]larger diameter than t 1e bore of the cylin er to permit the use oflarger valves, and the cylinder at each of the orts -26 and 27 isextended slightly beyond) the port in the form of a tubular art 29 withan internal shoulder 30 spaced rom the end of the tubular part andadjacent the valve seat portion 3l of the port.

Elbows or elbow-like parts 32 and 33 are secured to the cylinder plroperat the ports 26 and 27 respectively, t e part 32 forming the intakepassage and the part 33 forming the exhaust passage, for the motor. The

yonly difference between these two elbowlike parts is that the valvestem portion 34 of the elbow 33 is somewhat longer than in the elbow 32and a depression 35 is formed adjacent this portion so that the coolingwater may more readily reach it and thereby kee it cool.

ach of these elbows 32, 33, has a tubular part 36 adapted to fit withinthe tubular part 29 and have its'end abut against the shoulder 30, andan external flange 37 on.

the elbow is then adjacent the end of the tubular part 29 of itsrespective port. This arrangement of the tubular part 29 of the cylinderand the tubular part 36 of the elbow is illustrated in Fig. 11 beforethe welding operation which joins them takes place. As shown therein theflange 37 is slightly tapered so that there is not a close fit betweenit and the end of the tubular art 29, and for the purpose of making a weded joint between those two parts a piece of wire 38 is placed aroundthe loose joint and a welding heat is applied to the wire and theadjacent parts o'f the tubes whereby the wire and adjacent parts arefused together. This welded joint 1s shown particularly in Fig. 7 aswell as in Fig. 4.

Fig. 12, shows the same arrangement of tubular parts but in this casethe wire 38 is omitted and a welding heat is applied directl to thelange 37 changed slightly from the orm shown in Figs. 4, 7 and 11, andthe end of the tubular part 29 so that these two parts are directly'omed together. The joint.

1s shown in dotte lines at 39.

It will be seen that the two elbows 32 and 33 face oppositely and awayfrom the middle of the cylinder and their valve stem portions 34 extenddiagonally upward in the form of bosses 34 on the tops of the main bodyportions of the elbows. These elbows 1n ellect become part o'f thecylinder and they are surrounded by the water jacket together with therest of the cylinder. The water acket part 22 shown in Figs. 3 and 5will seen to have three openings 40, 41 and 42 formed therein and uponreference Lacasse to Fig. 4 in particular it will be seen that theseopenings are respectivel for the I lpwardly projecting boss 34t eprojectl'n end 43 of the elbow, and a boss 44 in wlnc the spark plugport 28 above referred to 1s formed. The jacket part 22 is secured tothese three parts of the cylinder by a novel welding method which willnow be described. Since the method of connecting the jacket to each ofthese three parts is the same, only one connection will be described indetail.

The tubular part 43 of the elbow 32 is shown in section in Figs. 7 and10. In Fig. 10 it will be seen that this tubular part o'f the elbow hasan external flange 45 machined on it and on-the flange is a rim or ring46 which is substantially the thickness of the sheet metal water 'acketto which it is to be connected. This rmg 46 is separated from andparallel to the outer wall of the tube and it is so arranged on theflange 45 as to leave part of that flange extending beyond the ring toform a shoulder 47. The water jacket 22 is now placed around thecylinder and thel tubular part 43 of the elbow and its ring 46 areinserted through the opening 41 so that the jacket rests against thebase of the ring 46 and the shoulder 47 formed by the extended part ofthe flange 45. A welding heat is now applied to the ring 46 and theadjacent part of the jacket 22 so that these metal arts flow togetherand form a welded joint. This joint is indicated in dotted lines at 48.Similar joints are made at 49 and 50 as shown in Figs. 4 and 7. Besidesthus weldin the two water jacket arts 22 to the cylin ers, the parts arewel ed together along the median plane of the cylinder as at 51, Fig. 4,and the lower ends of the jacket parts are secured as by welding, to adownwardly bent flange 52 formed on the cylinder as shown in Fig. 4.

For the purpose of supporting and inclosing the motor cam shaft at thetop of the cylinder a cam shaft housing 53'is provided and it is adaptedto be supported through its legs 54 upon the elbows 32 and 33 abovedescribed. As shown, the, means of support is in the form of a ring' 55welded as at 56 or otherwise secured to the projecting part 43 of eachof the elbows 32 and 33. The ring 55 is shown in detail in Fig. 9 and itwill be seen that a foot 57 extends upwardly therefrom, and as shown inFig. 4 is positioned to receive one of the legs 54 above referred to.These parts may be secured together by bolts 58. The ring 55 also formsan attaching flange 59 for the headers or manifolds which are adapted tobe secured to the elbows.

. It will be understood ,that other forms and modifications may be madewithout departlll Ell

ing trom the spirit or scope of the invention.
